Method and apparatus for controlling virtual screen

Abstract

A method and an apparatus for controlling a virtual screen in a touch screen device are provided. The method includes detecting a touch screen input on a screen view, the screen view displaying a partial area of the virtual screen on a display unit of the electronic device, determining whether the touch screen input is a stylus input or a touch input, the stylus input being executed by a user controlling a stylus and the touch input being executed by the user using a body part of the user, processing the stylus input as a manipulation input corresponding to the virtual screen when the touch screen input is the stylus input, and moving the screen view on the virtual screen in response to a touch movement of the touch input when the touch screen input is the touch input.

What is claimed is: 
     
       1. A method for controlling a virtual screen displayed on an electronic device, the method comprising:
 detecting a touch screen input on a screen view, the screen view displaying a partial area of the virtual screen on a display of the electronic device, the virtual screen comprising a viewing area that corresponds to the partial area displayed on the screen view and a non-viewing area that is not displayed on the screen view; 
 determining whether the touch screen input comprises a stylus input or a touch input, the stylus input being executed using a stylus and the touch input being executed using a finger of the user; 
 when it is determined that the touch screen input comprises the touch input, displaying a navigation window displaying navigation information corresponding to the screen view in the virtual screen in a partial region of the screen view; and 
 processing the touch screen input according to the determining, wherein the processing comprises:
 processing the stylus input as a data input corresponding to the virtual screen, in response to determining that the touch screen input corresponds to the stylus input, and 
 moving the screen view to view a different area of the virtual screen in response to a touch movement of the touch input, in response to determining that the touch screen input corresponds to the finger touch input. 
 
 
     
     
       2. The method as claimed in  claim 1 , wherein the moving of the screen view comprises moving the screen view at a speed corresponding to a speed of the touch movement of the touch input. 
     
     
       3. The method as claimed in  claim 2 , wherein the moving of the screen view comprises moving the screen view to an edge of the virtual screen corresponding to a direction of the touch movement of the touch input on the virtual screen when the touch movement of the touch input is performed at a speed greater than or equal to a predetermined speed and when the touch input is released. 
     
     
       4. The method as claimed in  claim 1 , wherein the displaying of the navigation window comprises:
 activating the navigation window when the touch input is detected; and 
 deactivating the navigation window when the touch input is at least one of not detected or terminated. 
 
     
     
       5. The method as claimed in  claim 1 , wherein the moving of the screen view comprises moving the screen view in a direction corresponding to a direction of the touch movement of the touch input. 
     
     
       6. The method as claimed in  claim 5 , wherein the direction corresponding to the direction of the touch movement is opposite to the direction of the touch movement. 
     
     
       7. An apparatus for controlling a virtual screen, the apparatus comprising:
 a touch screen display configured to detect a touch screen input on a screen view displayed by the touch screen display; and 
 at least one processor configured to:
 control the touch screen display to display the screen view, which displays a partial area of the virtual screen, the virtual screen comprising a viewing area that corresponds to the partial area displayed on the screen view and a non-viewing area that is not displayed on the screen view, 
 determine whether the touch screen input comprises a stylus input, which is executed using a stylus, or a touch input, which is executed using a finger of the user, 
 when it is determined that the touch screen input comprises the touch input, display a navigation window displaying navigation information corresponding to the screen view in the virtual screen in a partial region of the screen view, and 
 process the touch screen input according to the determining, wherein the processing of the touch screen input comprises:
 processing the stylus input as a data input corresponding to the virtual screen, in response to determining that the touch screen input corresponds to the stylus input, and 
 moving the screen view to view a different area of the virtual screen in response to a touch movement of the touch input, in response to determining that the touch screen input corresponds to the finger touch input. 
 
 
 
     
     
       8. The apparatus as claimed in  claim 7 , wherein the at least one processor is further configured to move the screen view at a speed corresponding to a speed of the touch movement of the touch input. 
     
     
       9. The apparatus as claimed in  claim 8 , wherein the at least one processor is further configured to move the screen view to an edge of the virtual screen corresponding to a direction of the touch movement of the touch input on the virtual screen when the touch movement of the touch input is performed at a speed greater than or equal to a predetermined speed and when the touch input is released. 
     
     
       10. The apparatus as claimed in  claim 7 , wherein the at least one processor is further configured to:
 activate the navigation window when the touch input is detected, and 
 deactivate the navigation window when the touch input is at least one of not detected or terminated. 
 
     
     
       11. The apparatus as claimed in  claim 7 , wherein the at least one processor is further configured to move the screen view in a direction corresponding to a direction of the touch movement of the touch input. 
     
     
       12. The apparatus as claimed in  claim 11 , wherein the direction corresponding to the direction of the touch movement is opposite to the direction of the touch movement.
